[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0025] Example 1: The utility model provides Figures 1 to 4 A foldable packaging box cover is shown, comprising a rectangular cover plate. The cover plate has two parallel first milling grooves 1 for folding, the first milling grooves 1 being symmetrically arranged, one on the left and one on the right, and both extending through the width of the cover plate. The cover plate also has two parallel second milling grooves 2 for folding, the second milling grooves 2 being symmetrically arranged, one on the front and one on the back, and both extending through the length of the cover plate.

[0026] The two first milling grooves 1 and the two second milling grooves 2 are both V-shaped grooves, and the two first milling grooves 1 and the two second milling grooves 2 are both opened by a trimming machine.

[0027] The two first milling grooves 1 and the two second milling grooves 2 together divide the box cover into a top cover plate 3, two wide side plates 5 along the width direction of the top cover plate 3 and symmetrical about the top cover plate 3, two long side plates 4 along the length direction of the top cover plate 3 and symmetrical about the top cover plate 3, and folding plates 6 located at the four corners of the box cover plate.

[0028] The two wide side panels 5 are folded 90 degrees inwardly toward the box cover along the first milling groove 1 , and simultaneously the two long side panels 4 are folded 90 degrees inwardly toward the box cover along the second milling groove 2 .

[0029] Each of the four folding plates 6 is separated from the connected wide side panels 5, and the cutting edges at the separation are all triangular. Each of the four folding plates 6 is folded 90 degrees inward toward the box cover along the first milling groove 1. The box cover is used to package steel 11, and the folding plates 6 are sandwiched between the steel 11 and the wide side panels 5.

[0030] The box cover is made of PE or PET board. In this embodiment, the trimming machine's blade specifications are adjusted according to the thickness of the box cover so as to mill out the first milling groove 1 and the second milling groove 2 for facilitating the wide side panel 5 and the long side panel 4 to be folded 90 degrees.

[0031] Working Principle of Example 1: When the box lid is folded, the two second milling grooves 2 are first used to fold the two long side panels 4 inward 90 degrees, that is, toward the steel material 11. Then, the two first milling grooves 1 are used to fold the four folding panels 6 inward 90 degrees, that is, toward the steel material 11. Finally, the two first milling grooves 1 are used to fold the two wide side panels 5 inward 90 degrees, that is, toward the steel material 11, and cover the folding panels 6. After folding, the box lid assumes a rectangular cover shape and is placed over the steel material 11.

[0032] Embodiment 2: This embodiment is a further optimization of embodiment 1, the difference being that the wide side panels 5 and the folding plates 6 are connected by fasteners.

[0033] The buckle includes a clamping column 12 , a sleeve seat 10 and a buckle cap 8 .

[0034] The clamping column 12 is fixedly mounted on the folding plate 6. The clamping column 12 is a semicircular arc cylinder, and a semicircular arc groove is provided on the clamping column 12 along the circumference.

[0035] The sleeve seat 10 is fixedly mounted on the outside of the wide side plate 5. An annular clearance groove is provided on the inner wall of the sleeve seat 10 along the circumferential direction, and the clearance groove is communicated with the inside of the sleeve seat 10.

[0036] The wide side plate 5 is provided with a through slot 7, which is communicated with the interior of the sleeve seat 10. The through slot 7 is matched with a clamping column 12, which passes through the through slot 7 and coaxially penetrates into the sleeve seat 10.

[0037] The clamping groove corresponds to half of the groove body of the clearance groove, and the corresponding parts of the clamping groove and the clearance groove together form a semicircular arc connecting groove with the clamping column 12 and the sleeve seat 10. The cross section of the connecting groove along the axial direction of the clamping column 12 is an inverted T-shape, and the matching semicircular arc clamping block 9 is slidably engaged in the connecting groove.

[0038] The buckle cap 8 and the end of the sleeve seat 10 away from the wide side plate 5 are coaxially rotated together, and the buckle cap 8 is fixedly connected to the clamping block 9.

[0039] The buckle cap 8 is threadedly connected with a bolt, and the bolt abuts against the clamping column 12 to limit the fit.

[0040] Working principle of embodiment 2: The working principle of this embodiment is based on the working principle of embodiment 1, in which during the process of the wide side panel 5 being folded inward 90 degrees, the clamping column 12 on the folding plate 6 passes through the through groove 7 and finally penetrates into the inverted sleeve seat 10.

[0041] At this point, twist the cap 8, causing the clamping block 9 to slide into the connecting groove. When the clamping block 9 is fully inserted into the connecting groove, tighten the bolt so that it presses against the clamping column 12, preventing the cap 8 from rotating. In this example, whether the clamping block 9 has fully entered the connecting groove can be determined by providing a through hole at the end of the cap 8 away from the sleeve seat 10. Visual inspection of the through hole can confirm whether the clamping block 9 is visible.

[0042] The other processes are the same as those in the first embodiment and will not be described in detail here.

[0043] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
